Abstract
The present disclosure relates to methods and apparatuses for assembling absorbent articles, and more particularly, methods and apparatuses for severing elastic in an advancing elastic laminate. A continuous elastic laminate may be formed by bonding elastic strands between a first continuous substrate layer and a second continuous substrate layer. As discussed in more detail below, the continuous elastic laminate may advance through a cutting apparatus that intermittently deactivates or severs the elastic strands of the elastic laminate along the machine direction.
Claims20
An apparatus for severing elastic strands in an elastic laminate, the apparatus comprising:
- an anvil roll including an outer circumferential surface;
- a cutting roll adjacent the anvil roll to define a nip between the anvil roll and the cutting roll, the cutting roll adapted to rotate about a first axis of rotation, wherein the outer circumferential surface and first axis of rotation are separated by a minimum distance D1;
- a blade connected with the cutting roll, the blade having a distal edge, and wherein the distal edge and the first axis of rotation are separated by a distance D2, wherein D2 is greater than D1 and defining an interference distance equal to the difference between D2 and D1;
- and
- wherein the distal edge of the blade is adapted to deflect the interference distance when moving through the nip and wherein the blade bends when the distal edge deflects by the interference distance.
